I would like that the "Reflow Lines/Block" and "Join lines" commands always work. Irrespective of the status of the "Line Breaking" (or any other) feature.
The line breaking feature is just a little aid that, while typing [and not pasting..], if the cursor gets right far enough then a newline is automatically inserted.
Without switching on this aid - and it neads to be witched on, infinite times!, again and again! - the user be unable to join lines? Why?
